Meetup was born out of the tragedy of 9/11, created as a way to help people in online communities connect in the real world and do meaningful things together. Over the past 10 years it has evolved into a network of almost 14 million members across 196 countries, organizing about 400,000 meetups a month.

This isn't to say the company hasn't hit some roadblocks. The company lost 95% of its activity when it started to charge for organizing a meetup, but co-founder and CEO Scott Heiferman has helped lead Meetup successfully through its new strategy.

The company is growing and doing interesting work, so we decided to check out where and how they do it.
